Hi Fabio M. Di Nitto,

FYI, I was just trying to set up gfs2 under pacemaker on Fedora 14
X86_64 and although yum provides '*/gfs_controld.pcmk' showed that I
needed the dlm-pcmk-3.0.17-1.fc14.x86_64 and
gfs-pcmk-3.0.17-1.fc14.x86_64 packages, yum install dlm-pcmk gfs-pcmk
would simply report "Nothing to do".  rpm -q showed that I didn't have
the packages installed.  I tried installing the cman package but that
didn't help.  I finally got it working by downloading the packages with
wget and installing them with rpm -ivh.

FYI, the dlm-pcmk and gfs-pcmk packages seem to be broken in the Fedora
14 x86_64 database at the moment.

No, those packages have been removed intentionally since pacemaker now
supports cman cluster manager and they become obsoleted.

So very short summary:

configure cman for clusternodes
start cman (including dlm/gfs controld)
tell pacemaker to use cman
configure fencing and all services.

Hello again Linux Clustering group,

So I've switched to using cman and I have an IP resource shared between my two nodes, but now I'm having trouble with GFS2 again. When I try to mount my active/active iscsi partition, I get:

[root eb2024-58 ~]# mount /dev/sda1 /mnt
gfs_controld join connect error: Connection refused
error mounting lockproto lock_dlm

I was able to create a partition on my iscsi device and format it with "mkfs.gfs2 -p lock_dlm -j 2 -t pcmk:iscsi /dev/sda1" and I can see the partition on both nodes with "fdisk -l", so I think everything iscsi is working.

I was said earlier that I needed to "start cman (including dlm/gfs controld)". I see the cman service and it is started and running, but the only dlm/gfs service that I see is one called "gfs2" and when I try to start it I get:

[root eb2024-58 ~]# service gfs2 start
GFS2: no entries found in /etc/fstab

So why can't I mount my iscsi partition and where are these elusive dlm/gfs crontrold services?

Thanks,
gb
